To @ZZ whom t may concern:

Be it known that we, DAVID I. Noimrs and Lnvr A.JorrNs'roN, citizens ofthe United States, residing at Middlebranch, Stark (/ounty, Ohio, andNorth Canton, Stark County, Uhio, respectively, have invented new anduseful Improvements in Sheaf Elevators, of which the following is aspecification.

This invention relates to sheaf elevators for elevating sheaves of grainor the like and has for its objects the provision of an elevator bywhich sheaves may be conveyed from a wagon or other source of supplyinto a barn or warehouse or stack and delivered at such points as may bedesiredto accomplish an even distribution of the material; and toprovide an elevator' which is adjustable in height to meet varyingconditions and to permit of the elevator being used within barns ofdifferent heights.

vVith these objects in view the invention consists in the novelconstruction and arrangement of parts, hereinafter described,illustrated in the accompanyingV drawings,

and particularly pointed out in the appendy ed claims, it beingunderstood that various changes in the form, proportions, size and minordetails of construction may be made within the scope of the appendedclaims, without departing from the spirit or sacrificing any of theadvantages of the invention. The invention thus set forth in generalterms is illustrated in the accompanying drawings forming part hereof,in which- Figure 1 is a side elevation of an elevator embodying theinvention.

Fig. 2 is a front elevation of the same. Fig. 3 is a perspective view ofthe adjustable frame, and

Fig. 4: is a transverse sectional view through the adjustable frame.

A practical embodiment of the invention isdisclosed in the accompanyingdrawings, forming a part of this specification in which similar numeralsof reference indicate corresponding parts throughout the several views.

The elevator is illustrated as mounted within a barn, a. portion ofwhich is indicated by the numeral 1. Upon a beam or the like indicatedat 2, a bearing 3 is mounted having a pivotal pin 4 which is carried bythe arm 5, which supports the upper end of the frame of the elevator.

This frame is adjustable vertically and comprises the board 6 having thechannel portion 7 thereon within which is slidably mounted the strip 6carried by the board 9, the upper portion of the channel members beingrecessed as shown at 10 in order to allow the board 9 to be locatedbetween said channel members and the board 6.

Spaced apertures 11 are provided in the boards 6 and 9 through whichbolts 12 are located to hold the parts in the desired adjustment andsimilar apertures 13 and 14 are provided in the channel portions 7 andstrip 8 respectively through which bolts 15 are located. v

The lower end of the board 6 is provided with a pair of spaced dependingarms 16 upon which are mounted the bearings 17 within which bearings isjournaled a shaft 18 having a beveled gear 19 mounted thereon. The gear19meshes with a beveled pinion 20 mounted upon the shaft 21 which isjournaled in suitable bearings 22 carriedby the arms 16. A. universaljoint 23 is provided between the shaft 21 and the shaft 24 which isjournaled in a suitable bearing 25 andl has mounted thereon a drivingpulley 26 arranged to be connected by a belt with any suitable source ofpower.

ik sprocket 27 is mounted upon the shaft 18 and connected by mea-ns ofan endless chain 28 with a sprocket 29 mounted upon the shaft 8O whichshaft is journaled in sultable bearings 31 carried upon the upper end ofthe strip 8, a sprocket 32Ybeing mounted upon the shaft 60, the boards 6and 9 being notched at 33 to receive said sprocket.

A. shaft 34 is ournaled in suitable bearings 35 provided in the arms 16and has mounted thereon a sprocket 36. A trough B8 is located at theupper end of the elevator and rearwardly disposed therefrom, brackets 89being carried by the forward end of said trough and pivotally mountedupon the shaft 30.

An arm 40 depends from the rear end of the trough 3S and has mountedtherein the sprockets l1 and 42, and a sprocket 43 is mounted upon thearm 5. An endless carrier chain all provided at intervals with carrierfingers 45 is located over the sprockets 36, 82, 41, 4-2 and 13, saidchainpassing upwardly upon the outer or forward side of the board 6 andrearwardly through the trough 38.- n arm e6 is connected to the strip 8and to any desired aperture 47 in the trough 38 thus providing forholding the trough at the desired angle with reference to the verticalframe of the elevator.

In the operation of the device the sheaves are thrown upon the carrieriingers 45 and carried upwardly to the top of the elevator' andrearwardly through the trough 38, being discharged at the rear end ofthe trough. The elevator' may be swung upon the pivot 4 and universaljoint 23 in order to evenly distribute the sheaves as they aredischarged from the trough. When it is desired to adjust the height ofthe elevator in order to install the same in barns oi diierent heights,

the bolts l2 and l5 are removed and the adjustable portion of thevertical frame comprising the strip 8 and board 9 is moved verticallywith reference to the channels 7 and board 6 and the bolts 12 and l5 areagain inserted inv suitable apertures through the members as abovedescribed.

From the foregoing it will be evident that a sheaf elevator is providedby means. of which sheaves of wheat and the like may be easily elevatedand evenly distributed, the conveyor being adapted to be easily andreadily adjusted in order that it may be installed in barns orwarehouses of diiierent heights.

Although the drawings and above specifications disclose the best mode inwhich We have contemplated embodying our invention, we desire to be notlimited to the details of such disclosure, for, in the further practicalapplication of our invention, many changes in form and construction maybe made, as circumstances require or experience suggests, withoutdeparting from the spirit of the invention, within the scope of theappended claim. v

We claim A sheaf elevator oit' the character described, comprising avertical frame including two members, one of said members comprising aboard and a channel portion carried thereby, the upper end of saidchannel portion having a recess, the other member of said upright framecomprising a board located within said recess and a strip connected toSaid board and located within the channel, means for connecting saidmembers together in any desired adjustment,` a sprocket mounted in thelower end of the first member, a second sprocket mounted in the upperend of the second member, a con- Y veyor chain located around saidsprockets and means for driving said chain. y

In testimony that we claim r,the above, we have hereunto subscribed ournames.
